Transcript of Owls

Emma Leff Owls Owls Emma Leff Diet Owls are almost exclusively carnivores. Owls are birds of prey. They like to eat mice, rats, frogs, insects and other small rodents. Larger owls also eat weasels, woodchucks, rabbits, snakes and sometimes geese Habitat Owls live in a large variety of places. Ranging from the desert to the Arctic Tundra. Owls live in grasslands, marshes, fields, tundras and many types of forests. Mating Owls mate in late winter and early spring. They call frequently in these mating periods. Owls are ready to mate about a year after hatching. Once a pair of owls have mated they look for a safe place to lay their eggs. Owlets Baby owls are called owlets. Owls lay two-seven eggs, depending on the species. Owl eggs are white and almost round. After six weeks they are ready to leave the nest to learn how to fly and hunt. Owls are nocturnal. They sleep all day and awake at dusk and go back to sleep at dawn. Owls have excellent vision and hearing. They can catch prey by sound alone. Hunting Snowy Owls and short-eared owls nest on the ground and burrowing owls nest underground. All other species nest high up in natural cavities in trees like woodpecker holes and deserted crow nests. Newborn owls are covered with soft, downy feathers. At first they only eat regurgitated food from their parents but soon they are fed torn bits of prey. Several hours after eating, an owl will cough up the indigestible bones and fur of the animal in the form of a pellet. The female has full responsibility for incubating and the male has the responsibility of providing food to his mate and owlets. A mated pair of owls will stay together for life. Owls attract a mate with their calls and showing off their feathers. For some species, the male will offer a gift of food. After about two weeks- two months of nesting the owlets hatch. As early as four months the owlets are experienced fliers and strong hunters. An owl may consume 5,000 rodents in a lifetime as well as other food. Owls inhabit every continent except Antarctica. Burrowing owls live in burrows made by skunks, ground squirrels, badgers and other digging animals. Fun Facts A group of owls is called a parliament. All owls have circle facial discs, except for the barn owl which has heart shaped facial discs. The smallest owl is the elf owl weighing only one once and the largest owl is the eagle owl with a wingspan of 6.6 feet! Lifetime The lifetime of an owl depends on the size and the species. Larger owls live longer than smaller owls. A large owl can live 30 years in the wild and 60 in a zoo. Sources Owls of North America- Francis Backhouse
